I've receintly bought a few copies of Vista on eBay. One of them was a Business-Full-Retail version. I've received the disc but since I'd like to install the 64 bit version I've ordered a 64 bit disc from Microsoft. I had to enter my DVD Key to order the disc. I called Microsoft, they made it seem like the 64 bit disc would come with another key. I can only presume that the key I used to order the disc is now no longer valid... Have any of you ordered alternative media from Microsoft? 1. Do they just send a new disc, or do they send a new key as well? 1b. What form does the new key take? Is it a nice COA sticker like all copies of XP used to have, or is it a cheap, ugly, yellow sticker affixed to the packaging? In the same conversation with Microsoft they also made it seem like the key that I already have would work with either a 32 or 64 bit install. 2. Do all full-retail keys work with either 32 or 64 bit installs? 3. What about OEM keys and/or upgrade keys? The main reason I ask, is I have another disc/key coming (a Premium-Full-Retail). I'm going to use this license to install a 64 bit version on another computer. 4. Am I going to need to order a completely seperate 64 bit DVD and key for this as well, or can I just use the key included with the 32 bit packaging and use any 64 bit DVD for the install? Thanks to anyone who can help! By the way, I've searched around the forums and the net for definative answers to these questions but as of yet have been unable to find any. I think I'll call MS again, and ask another CSR. I'll post her/his responses here...
